Sean Stannard-Stockton, the philanthropy adviser and author of the blog Tactical Philanthropy, notes that Twitter has added several social entrepreneurs to its list of suggested users.

In turn, it has probably created a new class of Twitter superstars from the world of philanthropy.

The list, which is filled largely with celebrities and big brands, is a starter kit of sorts for many Twitter newcomers. And those who are fortunate enough to become suggested users can expect a huge spike in followers.

“In separating the wheat from the chaff, Twitter has become a kingmaker of sorts, conferring online stardom to a mix of writers, gadget geeks, political commentators, and entrepreneurs,” The New York Times said in a recent story about the Twitter suggested user list. “After being named to the ‘suggested user’ list, Twitterers can gain more than 500,000 followers who get their brief updates via a cellphone or the Internet.”

So who made the list?

Mr. Stannard-Stockton, who is also a Chronicle columnist, points to Social Edge, the Skoll Foundation, Charity:Water, Kiva, Good magazine, and the charity Room to Read.
